Nigel Goodwin said:True! - considering building an 8088 computer because he think's a micro-controller isn't 'easy and flexible' - it's the (so called) 'super-regen' all over again :lol:
It is simpler sending data to a FLASH ROM than it is sending it to the AT89C2051, especially when I want as much through hardware as possible. After all, I/O through hardware is faster than I/O through a disk.How could building a computer using multiple chips possibly be any simpler than having everything you need in one package?
ah no. I went through 5 AT89C2051's and they have all failed. I tried making various programmers for them but those chips will not co-operate, plus the flexibility is low.there's always a learning curve to any device, such as microcontrollers, it sounds like instead of spending a little time figuring it out, you'd rather move to something more complicated, thinking that somehow it's going to be easier
I personally think programming a ROM is much easier. Also, I like external roms because If I decide to buy several ROMS loaded with code, I can easily insert one and load code on the fly.I really don't see what you find so appealing about external ROM... it takes just as much effort to program an external ROM chip as it does to program a microcontroller...
Yes and no.You're crazy man.
It is to a point. If I use 2 chips, I can debug easier, and determine which component is faulty if any chip heats up.considering building an 8088 computer because he think's a micro-controller isn't 'easy and flexible'

I have never taken a course in electronics... I've never had anyone teach me anything about electronics in person... Everything I have learned has been through the internet. I've burned out 0 microcontrollers since I have been using them (though I have burned out a few supporting chips). Perhaps, instead of random experimentation, learn before hand what the right way of doing it is, and do it that way. These microcontrollers are very robust devices, and if you are toasting them on a regular bases, you are doing something seriously wrong.Yes, because I learn electronics a lot more differently than the majority of the people. I learn through direct experimentation without ANYONE next to me in person helping me. I also learn that wrong actions generate burnt parts.
and No, because in real life, I'm not crazy. I'm just an ordinary guy.
My crazy comment was really just kidding around, but seriously, every post you make, makes me wonder what you are smoking. Is this for your project thats both radio modem and web server? cuz your questions in that thread really show you don't have any grasp of the software side of what you are trying to do or what hardware would be needed to make that odd project reality.
If you seriously want external ROM/RAM program addressable memory, you might want to look at the ARM chips. They are pretty popular now. JTAG programmable, 32 bit with external memory busses, and far more powerful than an 8088 and they don't require all those support chips to actually do anything.

I wouldn't mind moving to the ARM platform, but I just can't think of a project that I would like to do that requires that kind of processing power.

Uhh Nigel, this is 2006, not 1906! :lol:Nigel Goodwin said:You can do 100 feet with two bean cans and a ball of string! 8)
blind luck eh?I see no reason to think you will do any better with EEPROM's, in light of your bizarre programming ideas and 'blind luck' design techniques.

That doesn't even make sense. The only real difference in programming is that with the microcontroller it's programmed serially, with some control lines, instead of parallel. It still involves hardware signals, and if you're programming from a computer EITHER ONE involves copying the program off your hard disk...mstechca said:It is simpler sending data to a FLASH ROM than it is sending it to the AT89C2051, especially when I want as much through hardware as possible. After all, I/O through hardware is faster than I/O through a disk.
You make it sound like the failure was the fault of the chips... when in fact MANY people use microcontrollers without any problems, so it's pretty obvious that YOU are just programming them improperly. And what exactly do you even mean by "the flexibility is low"?mstechca said:ah no. I went through 5 AT89C2051's and they have all failed. I tried making various programmers for them but those chips will not co-operate, plus the flexibility is low.
I won't disagree that programming a ROM may be easier when you start from scratch... however, with a microcontroller, once you spend a little bit of time making a proper programmer, you don't have to deal with it again, and programming is as simple as plugging it in and clicking "program" in the PC software. Or are you planning to program your ROM chip manually using switches? :lol:mstechca said:I personally think programming a ROM is much easier. Also, I like external roms because If I decide to buy several ROMS loaded with code, I can easily insert one and load code on the fly.
That also doesn't make any sense. If you use one chip, you automatically know what chip is bad, without having to test multiple ones :lol: You also have to understand... it is not at all normal to be heating up a microcontroller... in a few years of using them, it's only happened ONCE to me, and that's because I crossed the power wires. If you can screw up and heat up a microcontroller, what makes you think you can't screw up and heat up an 8088 and/or a ROM chip?mstechca said:It is to a point.

Yes, that's the case with hobbies, especially electronics now a days. I mean why build most of this stuff we build when you can buy them now for cheap. It's getting pretty hard to find projects that have practical uses that you can't get at a dollar store. I don't think anyone here would criticise projects that have no point other than the interest in building the project, but that's not the case here.inaPICle said:Some things you do for no other reason than you just want to do it that way. Even if it is harder! If I wanted it easy I'd just grab a six pack, put my feet up and watch the game!

You must be talking about PIC's. the AT89C2051 is programmed parallel style.The only real difference in programming is that with the microcontroller it's programmed serially,
That I understand.if you're programming from a computer EITHER ONE involves copying the program off your hard disk...
If I just keep on using the AT89C2051, it would be difficult to use additional memory with it, which makes it difficult to do anything, especially if it is code memory. The new plan is to use an 80C51, and external memory with it. Also, reading the code is much easier this way.And what exactly do you even mean by "the flexibility is low"?
switches? LMAO! :lol:however, with a microcontroller, once you spend a little bit of time making a proper programmer, you don't have to deal with it again, and programming is as simple as plugging it in and clicking "program" in the PC software.

Anything can screw up, by anyone at anytime. In fact, when I bought my 25-pack NPN transistors, and later bought an 8-pack, the 8-pack worked great, and the 25-pack were complete garbage. I didn't realized the 25-pack failed until I tried each one of them all in the same circuit. I did the same with the 8-pack, and the 8-pack worked.If you can screw up and heat up a microcontroller, what makes you think you can't screw up and heat up an 8088 and/or a ROM chip?
I suppose I have violated Nigel's silent law #1: "Thou shall not go obsolete" :lol:That's what we keep telling you! - but you seem to want to use a dark-ages micro-processor rather than a modern micro-controller

Also, the 80C51 has extra ports as well.
